Agreed - these are not "competitions" any more it's way over the top marketing and they own you.
Once forgot to untick on of the boxes on one of these and the company rang multiple times convinced I wanted what they were flogging because I "inquired" about it.
These comps are their own worst enemy they've gone over the top and soon no-one will enter them any more…..
WARNING: after you put your details in it tries to sign you up for about 15 other companies emails/deals which you have to select NO for every one before it will enter you.
Really hate it when they do that :/
